Simple Example
local dir = ""
--assuming that our path is full of lovely files (it should at least contain main.lua in this case)
local files = love.filesystem.enumerate(dir)
for k, file in ipairs(files) do
print(k .. ". " .. file) --outputs something like "1. main.lua"
end
Recursively find and display all files and folders in a folder and its subfolders.
function love.load()
filesString = recursiveEnumerate("", "")
end
-- This function will return a string filetree of all files
-- in the folder and files in all subfolders
function recursiveEnumerate(folder, fileTree)
local lfs = love.filesystem
local filesTable = lfs.enumerate(folder)
for i,v in ipairs(filesTable) do
local file = folder.."/"..v
if lfs.isFile(file) then
fileTree = fileTree.."\n"..file
elseif lfs.isDirectory(file) then
fileTree = fileTree.."\n"..file.." (DIR)"
fileTree = recursiveEnumerate(file, fileTree)
end
end
return fileTree
end
function love.draw()
love.graphics.print(filesString, 0, 0)
end
